Chemist here: all the reds are correct but it would take so much time to explain why so many of the greens are super concerning. Every time I see this reposted it’s so concerning…I should just spend the 17 minutes and save a copy pasta response of everything horribly wrong with this.
Edit: page 1 on the SDS for pure sulfur.
I’m pretty sure that licking pure magnesium would make your tongue explode too.
Definitely not licking pure lithium, sodium, or any of the alkali (s-block) metals. My tongue is wet. That shit explodes in water, yo.
I have elemental magnesium (4 ~50g ingots, I keep it in my library in a barely-sealed ziplock). it’s shelf stable and doesn’t react violently with water. Want me to try licking it and let you know? (hint: at worst it’ll make a minuscule amount of milk of magnesia)
ETA: Would I stick my tongue in pyrophoric magnesium powder? No, and you wouldn’t do that with pyrophoric aluminum or zinc powders, either, but that doesn’t stop me from using (or licking) alumnum foil. Proof: https://invidious.darkness.services/watch?v=Q_4I30Nz_b0
The LD 50 for sulfur is 2000 MG per kilogram body weight. So you’d probably be fine licking it. You can’t just go off the msds.
